Patented Feb. '11, 913;

To all whom it may concern: Be it known that we, FREDERICK N. Pnssn andMILTON E. MoDoNNn'LL, citizens of the United States, residing atAltoona, in the county of Blair and State of Pennsylvania, have inventedcertain new and useful 11nd Polishing Purposes; and we do here decl'arethe following to be a full, clear, and

exact description of the invention, such as will enable others skilledin theart to-which it appertains to make and use the same.

This invention relates to a detergent for cleansing and polishingpurposes in general, butespecially adapted forcleaning and polishingvarnished and polished surfaces on coaches, vehicles, etc.

It has for its object to produce a composition of matter for thesepurposes yvhich willbe eflicient in action, comparatively inexpensive tomanufacture, and will leave a highlyfinished surface with an appearanceand odor suggesting a clean and' freshly varnished article.

To these ends, the invention consists in the novel combinations ofingredients more fully hereinafter disclosed and particularlypointcarbonates have been preferably removed. Care should'be taken toadd just enough' edout in the claims.

Incarrylng .out our invention, we preferably dissolve a fatty acid, suchas stearic acid in a neutral mineral 011, such as parafflu, or kerosene,or both, and also preferably apply some heat to aid in the solution whena solid acid is used.

the form of a Water solution from which all alkali to neutralize theacid present and to render 'the; subsequent emulsion neutral During theaddition of thesaid alkali, and";

during all the, subsequent'additions, the":

mixture is preferably suitabli: agitated, as

by a mechanical means, in order to form an emulsion and to prevent thewater and the; soap that is formedfromseparating from the mineral oil.Should this emulsion-justdisclosed be allowed to stand,. the said soaand water will finally -sep a-rateout an destroy the emulsion. Inorffder to prevent this, and tophold theeniulsioii permanently,

' with the above'j emulsion;

we next forl'nia fcolloidal mixtureof a suitable gum, such as tragacanthand water, andifiliwy .a suitable agitation thor oughly incorporate--this colloidal mixtii,

- more than a thick semi-solid paste, which ma be easlly dipped out ofthe container an' applied to the surface to be cleaned and" We nextpreferably add a caustic alkali, such as caustic soda, in

"thepolished surface. It certainly imparts a oremulsion thus producedwill hold its form indefinitely when the ingredients are properlyproportioned, and it -is found to be a very useful detergent without anyadditions for many purposes. However, for most purposes, in order tosave labor and to increase the rapidity of the action, we add finelydivided abradant from settling to the,

bottom, yet the soap when first formedtends to go mto a more or lessgelatinous mass,

and later appears to assume a more or less solid crystalline condition.After this crystalline. form has appeared, we again thoroughly agitatethe mass, so as to break up the soap and to form a paste. Later, uponstanding, although the soap may tend again to assume a solid form, yetit never forms polished. In fact, the paste-like 'form is easier ofapplication than would be a liquid form. In practice we prefer to addgum ammoniac a the gum tragacanth inmaking the above colloidal mixture,which materially aids in maintaining the emulsion, and.we believe 1 italso aids in imparting a luster to pieasant odor of a freshly varnishedsurface therparts cleaned. The abradant, of

course, can be added either before or after the "colloidal mixture isadded. When stearic -acidis used, we also preferably add some rdjoilflinorder toprevent the'soap -fronr 'beiiifg hard and stringy, but of courseany' othersuitable soapimay formed, or of course a ready made commercialsoap.- may be-suitably incorporated with the minfer .to' employlsomeparaffin oil 'for the purpose of givinggmore body to the vehicle;but,-of" lli"$8,. a large number of other oils couldbe used; a

The. proportions of the above ingredients be widely iaried, but we havefound the eraloil,- rwhenlkerosene is used, wealso presfollowing-proportions to give the most ex cellent results, and prefer.to employ-the same :Paraflin oil 197 lbs.,' kerosene .197 lbs., red oil13 lbs.,.stea;rio acid 9 lbs caustic soda '11 0253., water 141 lbs.,silef 72 .lbs

guni tragacunth' 8 oz,

Whenmixed as above, and the above: 1 m. portlons, for example, arefollowed, there is produced a pale yellowish pasty ma'x, which whenapplied to the varnished surfaces-oi railroad cars, automobiles," ete.,-is =-fo1jmd to clean the same efiiciently and quickly, without injury tothe-varnish, and to; leave a,
